Many thanks Tom. I will check it out

I am trying to model the dynamics of inoculum production of a fungal pathogen over the course of several cropping seasons. At the end of a given cropping season, the amount of inoculum is determined by the number of infected plants, and that inoculum will decay with time following an negative expone...

Hi,

Is there any workaround to use the "GET DATA AT TIME" function? I have the PLE+ version and this function is not available.

Thanks in advance!

Disease incidence represents the proportion of plants diseased out of the total of a plot, and therefore is dimensionless. the rate of disease, r, is 1/time (e.g., 1/day) I create a model with a stock (level) for disease incidence, but I have problems in including the exponential distribution of r o...

Hi all, I am trying to represent this mathematical expression into a SD-Vensim model: X(t)=∫X(t,r)f(r)dr The integral is defined between zero and R=2 (for example) X(t,r) represent a variable (disease incidence) at time t with a rate r, and is defined by the logistic equation X(t)=1/(1+(1-Yo/Yo)*EXP...

Thank you guys, I think it works with the MODULO function

Hello, I am trying to create a variable that accounts for the number of the month as in the following table: time step -> monthly counter 1-> 1 2 -> 2 3 -> 3 4 -> 4 5 -> 5 6 -> 6 7 -> 7 8 -> 8 9 -> 9 10 -> 10 11 -> 11 12 -> 12 13 -> 1 14 -> 2 15 -> 3 ... My simulation runs for 1200 months at time st...
